为什么 OpenGL 告诉我在运行后抛出“int”实例后调用终止？

Question

因此，我尝试使用 GLFW 制作一个 OpenGL 项目，并很高兴在 Visual Studio 代码中使用它，但是当我编译和运行该程序时，它会抛出错误。

我尝试在一个窗口中制作3个三角形，它起作用了，所以我尝试将VBO、VAO、EBO、shaderProgram、vertexShaderSource和fragmentShaderSource组织到单独的文件中，然后编译并运行它，我期望通常的结果，但会给我一个如果窗口没有响应，那么它将终止并给出错误。我不确定文件的女巫是否导致了这种情况，但我猜测是 main.cpp 文件：

#include"header/shaderClass.h"
#include"header/VAO.h"
#include"header/VBO.h"
#include"header/EBO.h"

//some vertex and indices arrays here

int main()
{
    // Initialize GLFW
    glfwInit();

    // Tell GLFW what version of OpenGL we are using 
    // In this case we are using OpenGL 3.3
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    // Tell GLFW we are using the CORE profile
    // So that means we only have the modern functions
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    // Create a GLFWwindow object of 800 by 800 pixels, naming it "YoutubeOpenGL"
    GLFWwindow* window = glfwCreateWindow(800, 800, "YoutubeOpenGL", NULL, NULL);
    // Error check if the window fails to create
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window" << std::endl;
        glfwTerminate();
        return -1;
    }
    // Introduce the window into the current context
    glfwMakeContextCurrent(window);

    //Load GLAD so it configures OpenGL
    gladLoadGL();
    // Specify the viewport of OpenGL in the Window
    // In this case the viewport goes from x = 0, y = 0, to x = 800, y = 800
    glViewport(0, 0, 800, 800);



    // Generates Shader object using shaders defualt.vert and default.frag
    Shader shaderProgram("default.vert", "default.frag");



    // Generates Vertex Array Object and binds it
    VAO VAO1;
    VAO1.Bind();

    // Generates Vertex Buffer Object and links it to vertices
    VBO VBO1(vertices, sizeof(vertices));
    // Generates Element Buffer Object and links it to indices
    EBO EBO1(indices, sizeof(indices));

    // Links VBO to VAO
    VAO1.LinkVBO(VBO1, 0);
    // Unbind all to prevent accidentally modifying them
    VAO1.Unbind();
    VBO1.Unbind();
    EBO1.Unbind();



    // Main while loop
    while (!glfwWindowShouldClose(window))
    {
        // Specify the color of the background
        glClearColor(0.07f, 0.13f, 0.17f, 1.0f);
        // Clean the back buffer and assign the new color to it
        glClear(GL_COLOR_BUFFER_BIT);
        // Tell OpenGL which Shader Program we want to use
        shaderProgram.Activate();
        // Bind the VAO so OpenGL knows to use it
        VAO1.Bind();
        // Draw primitives, number of indices, datatype of indices, index of indices
        glDrawElements(GL_TRIANGLES, 9, GL_UNSIGNED_INT, 0);
        // Swap the back buffer with the front buffer
        glfwSwapBuffers(window);
        // Take care of all GLFW events
        glfwPollEvents();
    }



    // Delete all the objects we've created
    VAO1.Delete();
    VBO1.Delete();
    EBO1.Delete();
    shaderProgram.Delete();
    // Delete window before ending the program
    glfwDestroyWindow(window);
    // Terminate GLFW before ending the program
    glfwTerminate();
    return 0;
}
